#QUERY parameters are the most common type of parameter, which is appended to the path of the URL when submitting a request.

#  TEMPLATE parameters are a flexible way of parameterizing the actual path of the request.

I have selected query parameter.We can specify the default value also.I have given 77 as the default value.
